Yeah, it looks like you're going to need a new tank and carb body. A common issue with these due to a reaction with the fuel line. Fortunately, those parts are still currently made.

Thank for the info, looks like need to spend another $30. Luckily they are still available.
Is this problem because of the fuel or anything else?

It's actually the older Vinyl fuel "LINE"... that caused this condition over the course of time. The newer "Silicone" fuel-line designed for "glow-fuel" use.. will not erode the plastic. You'll be able to get and keep that engine running again... don't worry. Congratulations on sourcing one of the finest and smallest IC glow-ignition engines ever made!

So I bought these two together new some 45+ years ago. Yup, $9.98. Never started them...just admired the engineering of them. The storage of both engines were in darkness and within the house.
NOT trying to stir the pot, but only trying to determine why mine with the original vinyl tubing did not deteriorate the plastic tank fuel nipples. The .010 vinyl fuel tubing looks more transparent than that of the .020, however both tank fuel nipples are still solid. Maybe sunlight and temperature may play a part (oxidization) in the deterioration process as opposed to just the presence of vinyl tubing?
Thoughts???

Did you oil the engines at some point? Usually the staining on the inserts indicated the engine was run. Fuel through the vinyl fuel line will clear out the acids from the plastic which rots out the Delrin tanks.

Re: $100 TD0.010
So, would it be safe to say that if one has one of these and decides to not use it for a while, it would be best to remove the fuel line so as to not rot out the plastic. Or is this only a problem with teh clear fuel line, meaning if one used small silicon fuel line it would not happen?

Jason, bought the engines new and never fueled them. At one time, I did remove the glow heads and placed a drop of 3 in 1 oil on top of the pistons and turned them over which explains the stain to the back of the placard.
Fuel through the vinyl fuel line will clear out the acids from the plastic which rots out the Delrin tanks.
Therefore it is the presence of fuel through the vinyl fuel line and not just vinyl in and of itself that causes the deconstruction of the Delrin tank?

I bought a .010 last year out of England that had been in storage since 1969 I think. It had similar problems. I replaced all the parts from Mecoa and it is just like new now. Beautiful motor hits about 30,000 RPM.

But we don't see any deteriotating on plastic backplates on tanked Bees. There is a vinyl pick-up line in tank, but no melting any. Your thoughts?

I have another 0.010 NIB, it does not have this problem.

Great observation. Supports that the presence of vinyl only is not potentially the single culprit leading to Delrin destruction.
Here's another .010 NIB example with no Delrin destruction.
Further thoughts as to the variable causing the Delrin tank and carburetor body problem?
